Premium digital tools for creators and small business owners — spreadsheets, planners and trackers that work straight out of the box.
Hi, I'm Marnus — the person behind MM Systems.
I started MM Systems with one simple goal: to build practical digital tools that save time, reduce overwhelm and help people grow their businesses with confidence.
What began as a collection of AI-powered design tools for print-on-demand sellers has grown into something much bigger.
Today, MM Systems is a full digital product shop with over 25 products — and growing every week.
Our shop now covers everything a creator, Etsy seller or small business owner needs to stay organised and make smarter decisions:
— 📊 Budget and finance spreadsheets — couples budgets, annual planners, savings trackers
— 📅 Content and business planners — social media, weekly, monthly and daily planning
— 🧠 ADHD-friendly life planners — habit trackers, routines, cleaning systems
— 💼 Business tools — freelancer CRM, bookkeeping, small business bundles
— 📈 Etsy seller tools — listing trackers, SEO spreadsheets, shop analytics dashboards
— 🎨 Printable PDFs — journals, wedding planners, working woman diaries, baby shower games
— 🖼️ Design resources — western PNG bundles, POD toolkits and content slogan packs
Every product we sell is built with the same three standards in mind:
✅ Simple enough for a complete beginner
✅ Powerful enough for a serious seller or entrepreneur
✅ Ready to use straight out of the box — no setup required
Whether you're just starting your side hustle, running a busy Etsy shop, managing a household budget as a couple, or building your brand on social media — there's something here for you.
Every tool in this shop is something I built because I needed it myself. That's the only standard we hold ourselves to.
Welcome to MM Systems. Let's build something great together.
